Drexel physicist Charles Lane, who worked on the 2005 geoneutrino detection, said the important thing was that science had finally offered concrete proof of a pivotal theory proposed more than 100 years ago by Ernest Rutherford, famous for discovering the atomic nucleus. ❋ Unknown (2010)
That made it well suited to see the even rarer appearance of a geoneutrino or two. ❋ Unknown (2010)
Both of the current experiments claiming geoneutrino discoveries were originally built for other reasons. ❋ Unknown (2010)
A geoneutrino is, it turns out, a particularly elusive type of an already elusive class of particles -- neutrinos -- most famous for inspiring John Updike to write a poem with the lines: "The earth is just a silly ball/To them, through which they simply pass." ❋ Unknown (2010)
Princeton University proclaimed this month that some of its physicists had helped discover an invisible particle known as a geoneutrino. ❋ Unknown (2010)
Others have suggested that geoneutrino detectors could be used to track how much plutonium is being burned in nuclear reactors -- thereby perhaps monitoring illicit activity. ❋ Unknown (2010)
For all their promise, these geoneutrino detectors won't be able to unearth the whole picture of Earth's interior. ❋ Unknown (2009)
To get a better idea of what's going on in the mantle - a dim and more distant flashlight - requires a geoneutrino detector situated in a place where the crust is only a few kilometers thick, like at the bottom of the ocean. ❋ Unknown (2009)
That's expensive, but it's about a factor of 10 less expensive than sending a spacecraft to another planet, points out David Stevenson, a planetary physicist at the California Institute of Technology in, who is not directly involved in the geoneutrino experiments. ❋ Unknown (2009)
Stevenson points out that all the geoneutrino detectors proposed share a shortcoming: They can't detect the geoneutrinos coming from radioactive potassium-40. ❋ Unknown (2009)
SNO+ is the furthest along of the up-and-coming geoneutrino experiments. ❋ Unknown (2009)
That's why the first geoneutrino detector was built near a cluster of reactors in, with an aim to further characterize antineutrinos. ❋ Unknown (2009)
Pending final approval of funding, the detector will be filled with a hydrocarbon-based scintillation fluid, which, when a geoneutrino is caught, will luminesce and trigger the detector. ❋ Unknown (2009)
But the new suite of geoneutrino detectors could pin down better numbers for the radioactive contribution. ❋ Unknown (2009)
Since then, the geoneutrino detector Borexino, located in an Italian mine, has come online. ❋ Unknown (2009)
's nuclear power plants are far enough away to not overwhelm the geoneutrino signal. ❋ Unknown (2009)
